Patent Document 1: Japanese Patent No. 2711964

However, the above-described conventional stirring and defoaming device and the stirring and defoaming method are used because the rotation axis is inclined at a predetermined angle in a manner intersecting with the revolution axis, and acts on the object to be processed contained in the container due to the revolution. The centrifugal force generated will mainly act on the face formed by the axis of rotation and the axis of revolution. Therefore, even if the container in which the object to be processed is revolved while rotating, the object to be treated remains in the specific place in the container (for example, in the place beside the rotation axis of the bottom of the container) without being mixed and stirred. As a result, there may be cases where the agitation is insufficient, and there is still room for improvement.

Therefore, the present invention has been developed in view of the above-described improvement points, and the technical problem thereof is to provide a stirring and defoaming device capable of reliably stirring and defoaming a workpiece contained in a container, and a stirring and degassing device. Bubble method.

The present invention has been developed in order to solve the above problems, and the stirring and defoaming apparatus of the present invention includes a turntable that is rotatable about a periphery of a revolution axis and is provided with a rotation axis, and a container that can accommodate a workpiece and is disposed on the turntable A container that is rotatable on the periphery of the rotation axis and that revolves by rotation of the turntable on the periphery of the revolution axis, characterized in that the rotation axis is located at a position that is twisted toward the revolution axis.

In the stirring and defoaming device of such a configuration, the container containing the object to be treated is placed on the turntable to be revolved around the periphery of the revolution axis, whereby the object to be treated in the container can be defoamed. Further, the object to be processed in the container can be stirred and defoamed by allowing the container to revolve while rotating on the periphery of the rotation axis.

Here, since the rotation axis is located at a position that is twisted to the revolution axis, the centrifugal force generated by the revolution applied to the object to be treated contained in the container mainly acts on the axis of rotation and is on the axis of revolution Parallel reference planes form the direction of intersection. Therefore, when the container in which the object to be processed is revolved while rotating, the object to be processed in the container will be subjected to centrifugal force and self-rotation due to the revolving action in a direction intersecting the reference surface. The effect of the generated centrifugal force is integrally mixed and stirred. Therefore, the object to be processed contained in the container can be surely stirred and defoamed.

In addition, the phrase "the axis of rotation is located at a position that is distorted to the axis of revolution" means that the position of the axis of rotation and the axis of revolution are not parallel and do not intersect, that is, the axis of rotation and the axis of revolution are not in the same plane. Positional relationship.

Preferably, the container is closed at least at one end in the central axis direction, and the central axis is aligned with the rotation axis, and the other end portion in the central axis direction is closer to the one end portion. The manner of the aforementioned revolution axis is provided on the aforementioned turntable.

Further, the stirring and defoaming method of the present invention is characterized in that the container accommodating the object to be processed is revolved around the periphery of the revolution axis, and is caused to be at the rotation axis at a position distorted to the aforementioned revolution axis. The periphery is rotated, and the object to be processed is subjected to stirring and defoaming treatment.

In the stirring and defoaming device and the stirring and defoaming method of the present invention, since the rotation axis is located at a position that is twisted with respect to the axis of revolution, the container containing the object to be processed is revolved while being rotated, and is housed in the container. The object to be treated is subjected to a centrifugal force generated by the revolution in a direction intersecting the reference surface and a centrifugal force generated by the rotation, and is integrally mixed and stirred to achieve a treatment. The object is surely stirred and defoamed.

An embodiment of the stirring and defoaming apparatus and the stirring and defoaming method of the present invention will be described in detail below with reference to the drawings.

Fig. 1 and Fig. 2 show the stirring and defoaming device 1 of the present embodiment. The stirring and defoaming device 1 can be used for agitating and defoaming treatment of a processed object composed of a plurality of materials. Further, the object to be treated is, for example, a material to be agitated, such as a medical material, an electronic component material, or a liquid crystal material, in order to avoid the presence of air bubbles as much as possible.

The stirring and defoaming device 1 is provided with a turntable 2 that is rotatable on the periphery of the revolution axis C1 and provided with the rotation axis C2, and a rotatable axis C2 that can accommodate the object to be processed and is disposed on the turntable 2 The container 3 that revolves around the periphery and revolves due to the rotation of the turntable 2 on the periphery of the revolution axis C1.

Further, as the driving means for revolving and rotating the container 3, although not illustrated in the present embodiment, various configurations can be employed. For example, a revolving motor that can rotate the turntable 2 on the periphery of the revolution axis C1 and a driving means that can rotate the container 3 around the periphery of the rotation axis C2 can be employed. Alternatively, a motor including a motor that can rotate the turntable 2 around the revolution axis C1 and a drive means for transmitting the driving force of the motor for rotating the container 3 around the rotation axis C2 can be used. In addition, the transmission means may be constituted by, for example, a combination of a pulley and a belt or a gear, or a revolving double-effect bearing may be used to make the revolution and the rotation independently independent of each other, and for example, a powder may also be used. A mechanism such as a brake can change the number of rotations of the rotation.

The turntable 2 is provided with a revolution axis C1 and a rotation axis C2, and a rotary turntable rotatable on the periphery of the revolution axis C1 is provided to extend along the thickness direction (up and down direction) to rotate around the revolution axis C1 The base portion 21 (the revolving direction arrow R1) and the receiving portion 22 (the rotation direction arrow R2) which is provided on the base portion 21 and rotatable around the rotation axis C2.

The base portion 21 is formed to be rotatable around the periphery of the revolution axis C1 that is provided to vertically pass through the central portion of the upper surface of the base portion, and a part of the upper peripheral portion is used as the inclined surface 211. This inclined surface 211 is a plane inclined by a predetermined angle with respect to a plane orthogonal to the revolution axis C1 (that is, the base surface P1), and is inclined downward as the closer to the revolution axis C1 is located. Further, the inclined surface 211 is provided in a symmetrical manner with respect to the revolution axis C1, and a pair is provided.

The receiving portion 22 is formed in a bottomed cylindrical shape, and is formed to rotate on the outer periphery of the rotation axis C2 with its central axis as the rotation axis C2. The receiving portion 22 is provided on the inclined surface 211 so that the rotation axis C2 is perpendicular to the inclined surface 211 of the base portion 21, and is formed in a pair in such a manner as to be symmetric with respect to the revolution axis C1. Therefore, the rotation axis C2 is provided in a pair in a manner symmetrical with respect to the revolution axis C1.

The positional relationship between the revolution axis C1 and the rotation axis C2 will be described in detail herein. The revolution axis C1 and the rotation axis C2 are in a positional relationship that is non-parallel and does not intersect, in other words, in a positional relationship that is not in the same plane, that is, in a so-called "distorted positional relationship".

Specifically, as shown in FIG. 1 and FIG. 2, the rotation axis C2 is inclined by a predetermined angle θ with respect to a plane orthogonal to the revolution axis C1 (that is, the base surface P1), and passes through the rotation axis. The separation distance between the plane parallel to the revolution axis C1 of C2 (i.e., the reference plane P2) and the revolution axis C1 is a predetermined distance X, and is set so as not to intersect the revolution axis C1. Further, the angle θ with respect to the rotation axis C2 of the base surface P1 can be selected from 10 degrees to 80 degrees, and is selected to be 50 degrees in the present embodiment. Further, the separation distance X between the revolution axis C1 and the reference plane P2 (that is, the separation distance between the revolution axis C1 and the rotation axis C2) is: a distance equal to the radius of the container 3, or slightly smaller than the radius of the container 3. Smaller distance. Therefore, the separation distance between the pair of rotation axes C2 is set in a symmetrical manner with respect to the revolution axis C1: a distance equal to or smaller than the diameter of the container 3.

The container 3 is a cylindrical body in which at least one end portion 3a in the central axis direction is closed. Specifically, the cylindrical body of the container 3 is closed in such a manner that one end portion 3a in the central axis direction is opened, and the other end portion 3b is closed in an openable manner, and the stirring and detachment can be performed. The object to be treated after the bubble treatment is taken out. More specifically, the container 3 is provided with a bottomed cylindrical container body 31 in which one end portion is closed and the other end portion is openable, and a lid portion that can close the opening of the other end portion of the container body 31. 32. Further, the number of preparations of the containers 3 corresponds to the number of the receiving portions 22, and two are prepared in the present embodiment.

This container 3 is disposed on the turntable 2 to be rotatable on the periphery of the rotation axis C2. Specifically, the container 3 is fitted to the receiving portion 22 so as to be disposed on the turntable 2 such that its central axis coincides with the central axis of the receiving portion 22 (that is, the rotation axis C2). Therefore, the container 3 revolves around the periphery of the revolution axis C1 because of the rotation of the turntable 2 on the periphery of the revolution axis C1 (the revolution direction arrow R1), and is rotated by the periphery of the rotation axis C2 by the receiving portion 22, The periphery of the rotation axis C2 is rotated (rotation direction arrow R2). Further, in the present embodiment, the container 3 is provided such that the other end portion 3b (the lid portion 32 side) that can be opened is on the downstream side in the revolution direction, and the one end portion 3a (bottom side) that is not opened to be sealed is attached. On the upstream side of the revolution direction.

Further, in the present embodiment, the length of the container 3 in the direction of the rotation axis C2 is set such that, in a state where the container 3 is placed on the turntable 2, the container 3 as a whole is located closer to the reference line C1 than the reference axis C1. Such a length when the plane orthogonal to the plane P2 (that is, the boundary interface P3) is located further on the upstream side in the revolution direction. That is, when the container 3 is placed on the turntable 2, the other end portion 3b is closer to the revolution axis C1 than the one end portion 3a.

The agitating and defoaming device 1 having the above-described structure mounts the container 3 that has been housed with the object to be processed to the receiving portion 22 of the turntable 2, and rotates the turntable 2 around the revolution axis C1 to cause the container 3 to revolve. The centrifugal force generated by the revolution will act on the object to be treated, and the object to be treated will be pressed toward the inner surface of the container 3 to cause the air bubbles existing inside the object to be moved toward the upper surface of the object to be released. Therefore, the object to be treated can be subjected to a defoaming treatment (defoaming step).

Further, when the container 3 is rotated while rotating around the rotation axis C2, the centrifugal force generated by the revolution and the centrifugal force generated by the rotation will be applied to the object to be processed, and the object to be processed may be directed toward the container 3. The inner surface is pressed and the mixture is stirred and rotated, and the object to be treated is subjected to stirring and defoaming treatment (stirring and defoaming step). Further, in the present embodiment, the direction of revolution R1 of the container 3 is set to be opposite to the direction of rotation R2. Specifically, the direction of revolution R1 of the container 3 is set such that when viewed from the upper side in the direction of the revolution axis, In the clockwise direction, the rotation direction R2 is set to be in the counterclockwise direction when viewed from the other end side in the rotation axis direction. However, the present invention is not limited thereto, and the revolution direction R1 and the rotation direction R2 may be set to In the same direction. In other words, the revolution direction R1 is centered on the revolution axis C1, and can be set in the clockwise direction (specifically, the other end portion 3b of the container 3 (the cover portion 32 side) is located on the downstream side in the revolution direction, and the one end portion 3a (bottom side) is in the direction of rotation on the upstream side in the revolution direction); it may be set in the counterclockwise direction (specifically, the other end portion 3b of the container 3 (the side of the cover portion 32) is in the revolution direction On the upstream side, the one end portion 3a (bottom side) is located in the rotation direction on the downstream side in the revolution direction), and similarly, the rotation direction R2 is also set to be the clockwise direction or the counterclockwise direction centering on the rotation axis C2, and The revolution direction R1 and the rotation direction R2 may be set to any combination.

Here, the action of the stirring and defoaming method performed by the stirring and defoaming device 1 of the present embodiment will be described in detail with reference to FIGS. 3(A) to 3(D), and the conventional stirring is performed. The effects of the agitation and defoaming methods performed by the cum defoaming device 100 are compared. In addition, FIGS. 3(A) and 3(B) show a conventional stirring and defoaming device 100, and FIGS. 3(C) and 3(D) show the stirring and defoaming device of the present embodiment. For the sake of convenience of explanation, each drawing is expressed in a simplified schematic manner.

In the conventional stirring and defoaming device 100, the rotation axis C200 is inclined at a predetermined angle with respect to the base plane orthogonal to the revolution axis C100, and intersects with the revolution axis C100, so the revolution axis C100 will be located on the plane as the reference plane P200. In other words, the plane formed by the rotation axis C200 and the revolution axis C100 will become the reference plane P200. Therefore, the centrifugal force generated when the container 300 is revolved mainly acts along the reference plane P200 (as indicated by an arrow F100). For example, among the centrifugal forces generated by the revolution, the centrifugal force acting on the point at which the bottom of the container 300 intersects the rotation axis C200 acts along the reference plane P200. Therefore, the stirring and defoaming method performed by the conventional stirring and defoaming device 100 is to revolve the container 300 on the outer peripheral side of the revolution axis C100 while constituting the rotation axis C200 which is inclined obliquely to the revolution axis C100. In the method of rotating the periphery of the periphery, as shown in FIG. 3 (A) and FIG. 3 (B), the object to be processed accommodated in the container 300 is directed outward in the direction of the revolution of the reference plane P200 (arrow) The direction of F100 is pressed toward the inner surface of the container 300, and is mixed and stirred by the centrifugal force generated by the rotation. As a result, for example, the processed object located beside the rotation axis C200 at the bottom of the container 300 sometimes cannot be sufficiently mixed and stirred, and the final result will cause the stirring to be insufficient.

On the other hand, in the stirring and defoaming device 1 of the present embodiment, since the rotation axis C2 is located at a position that is twisted with respect to the revolution axis C1, the plane of the reference plane P2 is separated from the revolution axis C1 by a predetermined distance X and kept parallel. . Therefore, the centrifugal force acting when the container 3 revolves mainly acts on the direction intersecting the reference plane P2 (the direction of the arrow F1). For example, among the centrifugal forces generated by the revolution, the centrifugal force acting on the point at which the bottom of the container 3 intersects the rotation axis C2 acts in a direction crossing the reference plane P2. Therefore, the stirring and defoaming method performed by the stirring and defoaming device 1 of the present embodiment is such that the container 3 containing the object to be processed revolves around the periphery of the revolution axis C1 and is positioned at the aforementioned axis of revolution The method of rotating the periphery of the rotation axis C2 at the position where the C1 is twisted, as shown in FIG. 3(C) and FIG. 3(D), the object to be processed contained in the container 3 is directed to the reference plane P2. The outer direction of the cross-diameter in the direction of the radial direction (the direction of the arrow F1) is pressed against the inner surface of the container 3, and the centrifugal force generated by the rotation is received, so that all of them are mixed and stirred without any loss, and it is possible to obtain sufficient Stirring.

Further, as shown in FIGS. 3(A) and 3(C), the object to be processed in the stirring and defoaming process performed by the stirring and defoaming device 1 of the present embodiment is more conventional than the conventional one. The object to be processed in the stirring and defoaming process performed by the agitation and defoaming device 100 is further squeezed toward the central axis of the container 3, specifically, the cover which is expanded and reaches closer to the container 3. The state of the portion of the portion 32. Therefore, the object to be treated in the stirring and defoaming process of the present embodiment is in contact with the inner surface of the container 3 in a larger amount than the object to be treated in the conventional stirring and defoaming process.

In addition, although the present embodiment is directed to the case where the distance between the pair of rotation axes C2 is equal to or slightly smaller than the diameter of the container 3, the present invention is not limited thereto, and may be applied to the container 3 as compared with the container 3. The larger diameter case. For example, as shown in FIG. 4 and FIG. 5, by setting the distance between the revolution axis C1 and the reference plane P2 to be larger than the radius of the container 3, it is possible to form a symmetry with respect to the revolution axis C1. The separation distance between the pair of rotation axes C2 set in such a manner is set to be larger than the diameter of the container 3. By adopting such a configuration, when the length of the container 3 in the direction of the central axis is long, specifically, in a state where the container 3 is placed in the receiving portion 22, even at least one portion of the other end portion 3b When the arrival reaches the downstream side of the revolving direction, the one end portion 3a is located at a length closer to the upstream side in the revolving direction than the boundary interface P3, and is provided separately on the pair of receiving portions 22. In the case of the container 3, the containers 3 are arranged in a three-dimensional cross arrangement that does not contact each other. Therefore, it is possible to avoid an increase in size of the stirring and defoaming device 1, and to achieve compactness and miniaturization.

Further, in the present embodiment, the case where the pair of containers 3 are arranged to be symmetrical with respect to the revolution axis C1 will be described. However, the present invention is not limited thereto, and may be arranged such that, for example, the rotation axes C2 of both sides are kept parallel to each other or Cross each other.

Further, the present embodiment has been described with respect to a case where the container 3 is provided on the turntable 2 such that the other end portion 3b is closer to the revolution axis C1 than the one end portion 3a. However, the present invention is not limited thereto. It is provided, for example, that the one end portion 3a is closer to the revolution axis C1 than the other end portion 3b. Alternatively, it is provided that the one end portion 3a and the other end portion 3b maintain the same separation distance with respect to the revolution axis C1.

In the present embodiment, the case where the container 3 is provided in two is described. However, the present invention is not limited thereto, and for example, only one or three or more may be provided.

In the present embodiment, the case where the container 3 is a cylindrical body will be described. However, the present invention is not limited thereto, and may be, for example, a bowl having a substantially hemispherical shape. In this case, the opening is passed through the opening. The center of the center and the axis of the bottom become the central axis.

In the present embodiment, the case where the container 3 has a cylindrical shape will be described. However, the present invention is not limited thereto. For example, the container may have a polygonal cylindrical shape.

Further, in the present embodiment, the case where the one end portion 3a of the container 3 in the direction of the central axis thereof is sealed so as not to be opened, and the other end portion 3b is sealed so as to be openable is not limited. Here, it is also applicable to the case where both end portions 3a, 3b are sealed in an openable manner; and the one end portion 3a is sealed in an openable or non-openable manner, and the other end portion 3b is kept open. Happening. Further, as the container in which both end portions 3a and 3b are openably closed, for example, a syringe is exemplified.

In the present embodiment, the case where the container 3 is provided on the upper surface side of the turntable 2 is described. However, the present invention is not limited thereto, and may be applied to, for example, a case where the container 3 is provided on the lower surface side.

In addition, although the present embodiment has been described with respect to the case where the revolution axis C1 is formed in the vertical direction, the present invention is not limited thereto, and may be applied to, for example, a case where it is formed in the left-right direction.
